OpenForge 2.0 Wood Floor House Up & down Stone Stairwell

OpenForge 2.0 OpenLock 4
Needed a second floor spiral stair in the corner of a house, going down to the first floor and up to a third. This would be a second wood floor of a house. Stacking a third floor I would leave the tile missing from the corner to depict the top of the stairwell. Avoiding a print with supports, modified a previous stair with a stone wall "stairwell" to create a roleplaying terrain feature/accessory to depict a 3/4 turn (270 deg) spiral staircase in the corner of a room.
